+# OmniTab
+
+OmniTab is a table-based QA model proposed in [OmniTab: Pretraining with Natural and Synthetic Data for Few-shot Table-based Question Answering](https://arxiv.org/pdf/2207.03637.pdf). The original Github repository is [https://github.com/jzbjyb/OmniTab](https://github.com/jzbjyb/OmniTab).
+
+## Description
+
+`neulab/omnitab-large` (based on BART architecture) is initialized with `microsoft/tapex-large` and continuously pretrained on natural and synthetic data.
+
+## Usage
+
+```python
+from transformers import AutoTokenizer, AutoModelForSeq2SeqLM
+import pandas as pd
+
+tokenizer = AutoTokenizer.from_pretrained("neulab/omnitab-large")
+model = AutoModelForSeq2SeqLM.from_pretrained("neulab/omnitab-large")
+
+data = {
+    "year": [1896, 1900, 1904, 2004, 2008, 2012],
+    "city": ["athens", "paris", "st. louis", "athens", "beijing", "london"]
+}
+table = pd.DataFrame.from_dict(data)
+
+query = "In which year did beijing host the Olympic Games?"
+encoding = tokenizer(table=table, query=query, return_tensors="pt")
+
+outputs = model.generate(**encoding)
+
+print(tokenizer.batch_decode(outputs, skip_special_tokens=True))
+# [' 2008']
+```
